VIIRS/JPSS1 NDVI 16-Day 1km (VJ113A2 V002), Native

16-day Normalized Difference Vegetation Index (NDVI) from the VIIRS sensor on NOAA-20 (JPSS-1), at 1 km resolution on the global sinusoidal grid. Each composite selects the best available observation per pixel over the 16-day period. The product continues the MODIS vegetation index record. Only the NDVI layer of the NASA LP DAAC VJ113A2 version 2 product is stored here, without further processing.

See also the NASA Earthdata dataset page and the VNP13 User Guide and ATBD for methodology and caveats.

Data organization

All tiles of a composite share one folder; the tile is part of the filename, e.g. VJ113A2.A2018001.h20v08.002.2022352115611_VIM.tif (composite start A<year><day-of-year>, tile h20v08).

Usage

NDVI is stored as scaled integers: multiply by 0.0001 and mask -15000 to get values in [-1, 1]. Tiles are mosaicked on load, in the native sinusoidal CRS unless you pass crs= and resolution=.

License
